The Second Tyrannic War

At the beginning of the Second Tyrannic War, it was infested with Genestealers. A genestealer cult, operating under the name, "the Brotherhood," instigated a rebellion on the planet that caught the attention of InquisitorAgmar. The Brotherhood had control of the planet by the time Agmar arrived in the system. The inquisitor petitioned the Space Marine chapter, the Ultramarines, to help put down the rebellion. Marneus Calgar, chapter master of the Ultramarines, arrived 39 days later aboard the space marine battle barge, Octavius. Eventually, with the combined support of the Ultramarines, PDF forces and the Imperial Guard, the inquisition successfully destroyed the invasion and cleansed the planet of all Genestealers.[1]
